Finally - a US TV series based on Mitchell and Webb's sketch about the Emergency Broadcasting Service gameshow that takes place after The Event!

No, not really. But who's to say that The Event in this new series isn't what led to the destruction of civilisation as we know it? Sci-fi fans feeling, er, lost after Lost, and who still hanker after the good old days of The X Files and government cover-ups, this one has your name all over it.

Things start confusingly - deliberately so - hopping about in time with captions telling us: "13 months earlier", or "Eight days earlier".

Could it be that The Event, whatever it is, has somehow robbed humans of the ability to simply tell a story from beginning to end?

In tonight's first two episodes we must try to make sense of a plane hijacking, and an assassination attempt - though it turns out neither of these are The Event itself. But then nothing is what it appears to be at first.

The good news is that by episode two, we've got some answers - so we can only hope that this series will live up to its early promise and not disappear up its own black hole like so many others in the past.

The cast includes LA Law's Blair Underwood as the US President and Laura Innes from ER, plus Jason Ritter and Sarah Roehmer as Sean Walker and Leila Buchanan - a young couple for whom life is about to get insanely complicated.

As they'd say on That Mitchell And Webb Look: Stay Indoors! And watch this.
